摘要：
he paper discusses the problem of ensuring the QoS performance in wavelength-routed optical burst-switched (WR-OBS) networks under single link failures. The provision of IP services run over high-speed optical backbones should be resilient to faults in the network, hence the importance of WR-OBS survivability investigation. A failure-compensating scheduling residing in the WR-OBS control node, is proposed and analysed in terms of burst blocking probability and burst scheduling delay increment. The WR-OBS wavelength over-provisioning maintaining guaranteed QoS is also studied as a function of network physical connectivity.
